Abstract

In a telecommunication system where a plurality of user channels are processed in a time-slotted manner, a transmitter and receiver can perform bit error rate measurements for a plurality of user channels by only using one PN-generator (T-PN) and one state memory (ISM). A read/write means (R/W) is provided for reading to and writing from to the state memory (ISM). Whenever a timing means (TM) detects the beginning of a new time-slot, the read/write means (R/W) reads out a last-stored phase state from the state memory (ISM). When detecting the end of the respective time-slot, the phase state then present in the PN-generator (T-PN) is stored into the state memory (ISM) to be used for re-initialization of the PN-generator (T-PN) for the same time-slot in a succeeding frame. Thus, one PN-generator (T-PN) is enough for generating PN-sequences for a great number of user channels.
